Abstract

A data decoding apparatus and the method and a data reproduction apparatus which reduces capacity of a memory used for decoding and speedily accesses to data to be read. In a data decoding apparatus (50) and the method which decodes coded data (S2) which is recorded in a recording medium (2), the coded data (S2) read from the recording medium (2) is stored in a memory used for decoding (51), data information of data to be read is detected from decoded data which is generated in the middle of decoding the coded data (S2), the data information is stored in a data information storage means and the output of decoded data (S10) is controlled on the based on the data information, thereby the output of the decoded data (S10) is controlled based on the data information independent of decoding of the coded data (S2).
